摘要：
A titanium nitride layer, produced by arc ion plating method, was synthesized to give Eu-N codoped titania catalyst by using micro-arc oxidation (MAO) in the H2SO4/Eu(NO3)(3) mixture solution. The N-Eu-incorporated anodic TiO2 film exhibited significantly enhanced photocatalytic activity for dye degradation, which was ascribed to the synergistic effects of the high photo absorbance response and the new electronic state of the TiO2 band gap induced by the N and Eu codoping.
